Use (setq-local mode-line-position nil)
in the mode-hook.
Example:
(define-derived-mode my-mode nil "my") ;; Our playground.
(defun remove-mode-line-position () ;; That's the thing you actually need.
"Set `mode-line-position' buffer-locally to nil."
(setq-local mode-line-position nil))
(add-hook 'my-mode-hook #'remove-mode-line-position) ;; Usage example.
If you create a new buffer with C-x b *mybuf*
RET and call M-x my-mode
RET the position info in the modeline disappears for buffer *mybuf*
but for no other buffer.
